HPC Tools failed to install on a Win2008 SP1 Ent. Cluster Node

Question

The cluster is running. The cluster Service is running under the local service Account. the sql service is running under a domain account.

When i'm installing the HPC Pack on the active node i get an error "HPC Setup encountered an error while interacting with the MS Win 2008 Failover Cluster. The Failover Cluster Service must be running on this node and an active Member of its cluster in order for hpc setup to continue".
